-[Internal Max-Stale](#internal-max-stale) | Controls how long past the normal expiration time a cached asset may be served from a POP when the POP is unable to revalidate the cached asset with the origin server.
-[Partial Cache Sharing](#partial-cache-sharing) | Determines whether a request can generate partially cached content.
-[Prevalidate Cached Content](#prevalidate-cached-content) | Determines whether cached content is eligible for early revalidation before its TTL expires.
-[Refresh Zero-Byte Cache Files](#refresh-zero-byte-cache-files) | Determines how an HTTP client's request for a 0-byte cache asset is handled by the POPs.
-[Set Cacheable Status Codes](#set-cacheable-status-codes) | Defines the set of status codes that can result in cached content.
-[Stale Content Delivery on Error](#stale-content-delivery-on-error) | Determines whether expired cached content is delivered when an error occurs during cache revalidation or when retrieving the requested content from the customer origin server.
-[Stale While Revalidate](#stale-while-revalidate) | Improves performance by allowing the POPs to serve stale client to the requester while revalidation takes place.

-## Optimize
-
-These features determine whether a request will undergo the optimizations provided by Edge Optimizer.
-
-Name | Purpose
------|--------
-Edge Optimizer | Determines whether Edge Optimizer can be applied to a request.
-Edge Optimizer – Instantiate Configuration | Instantiates or activates the Edge Optimizer configuration associated with a site.
-
-### Edge Optimizer
-**Purpose:** Determines whether Edge Optimizer can be applied to a request.
-
-If this feature has been enabled, then the following criteria must also be met before the request will be processed by Edge Optimizer:
-
-- The requested content must use an edge CNAME URL.
-- The edge CNAME referenced in the URL must correspond to a site whose configuration has been activated in a rule.
-
-This feature requires the ADN platform and the Edge Optimizer feature.
-
-Value|Result
--|-
-Enabled|Indicates that the request is eligible for Edge Optimizer processing.
-Disabled|Restores the default behavior. The default behavior is to deliver content over the ADN platform without any additional processing.
-
-**Default Behavior:** Disabled
-
-
-### Edge Optimizer - Instantiate Configuration
-**Purpose:** Instantiates or activates the Edge Optimizer configuration associated with a site.
-
-This feature requires the ADN platform and the Edge Optimizer feature.
-
-Key information:
-
-- Instantiation of a site configuration is required before requests to the corresponding edge CNAME can be processed by Edge Optimizer.
-- This instantiation only needs to be performed a single time per site configuration. A site configuration that has been instantiated will remain in that state until the Edge Optimizer – Instantiate Configuration feature that references it is removed from the rule.
-- The instantiation of a site configuration does not mean that all requests to the corresponding edge CNAME will automatically be processed by Edge Optimizer. The Edge Optimizer feature determines whether an individual request will be processed.
-
-If the desired site does not appear in the list, then you should edit its configuration and verify that the Active option has been marked.
-
-**Default Behavior:** Site configurations are inactive by default.

-[Maximum Keep-Alive Requests](#maximum-keep-alive-requests) | Defines the maximum number of requests for a Keep-Alive connection before it is closed.
-[Proxy Special Headers](#proxy-special-headers) | Defines the set of CDN-specific request headers that are forwarded from a POP to an origin server.
-
-## Specialty features
-
-These features provide advanced functionality for advanced users.
-
-Name | Purpose
------|--------
-[Cacheable HTTP Methods](#cacheable-http-methods) | Determines the set of additional HTTP methods that can be cached on the network.
-[Cacheable Request Body Size](#cacheable-request-body-size) | Defines the threshold for determining whether a POST response can be cached.
-[User Variable](#user-variable) | For internal use only.
-
-## URL features
-
-These features allow a request to be redirected or rewritten to a different URL.
-
-Name | Purpose
------|--------
-[Follow Redirects](#follow-redirects) | Determines whether requests can be redirected to the hostname defined in the Location header returned by a customer origin server.
